Operating instructionsS3G450-LC28-51Translation of the original operating instructions4.5 Checking connections; Ensure isolation from supply (all phases).; Make sure a restart is impossible; Check the cables for proper fit.4.6 Switching on the deviceThe device may only be switched on if it has been installed properly andin accordance with its intended use, including the required safetymechanisms and professional electrical hookup. This also applies fordevices which have already been equipped with plugs and terminals orsimilar connectors by the customer.WARNINGHot motor housingRisk of fire→ Ensure that no combustible or flammable materials arelocated close to the fan.; Before switching on, check the device for visible external damageand make sure the protective devices are functional.; Check the fan's air flow paths for foreign matter and remove anyforeign matter found.; Apply the nominal supply voltage.; Start the device by changing the input signal.NOTEDamage to the device from vibrationBearing damage, shorter service life→ Low-vibration operation of the fan must be ensured over theentire speed control range. #Severe vibration can arise forinstance from inexpert handling, transportation damage andresultant imbalance or be caused by component or structuralresonance. #Speed ranges with excessively high vibrationlevels and possibly resonant frequencies must bedetermined in the course of fan commissioning. #Either runthrough the resonant range as quickly as possible withspeed control or find another remedy.# Operation withexcessively high vibration levels can lead to prematurefailure.4.7 Switching off the deviceSwitching off the device during operation:; Switch off the device via the control input.; Do not switch the motor (e.g. in cyclic operation) on and off via powersupply.Switching off the device for maintenance:; Switch off the device via the control input.; Do not switch the motor (e.g. in cyclic operation) on and off via powersupply.; Disconnect the device from the power supply.; When disconnecting, be sure to disconnect the ground connection last.5. INTEGRATED PROTECTIVE FEATURESThe integrated protective functions cause the motor to switch offautomatically in the event of the faults described in the table.Fault Safety feature description/functionRotor position detection error An automatic restart follows.Blocked rotor ; After the blockage isremoved, the motor restartsautomatically.Line undervoltage (line voltageoutside of permitted nominalvoltage range); If the line voltage returns topermitted values, the motorrestarts automatically.6. MAINTENANCE, MALFUNCTIONS, POSSIBLECAUSES AND REMEDIESDo not perform any repairs on your device. Send the device to ebm-papst for repair or replacement.WARNINGLive terminals and connections even with deviceswitched offElectric shock→ Wait five minutes after disconnecting the voltage at all polesbefore opening the device.CAUTIONIf control voltage or a stored speed set value is applied,the motor will restart automatically, e.g. after a powerfailure.Risk of injury→ Keep out of the device’s danger zone.# When working onthe device, switch off the line voltage and ensure that itcannot be switched back on.→ Wait until the device comes to a stop.→ After working on the device, remove any tools or otherobjects from the device.If the device is out of use for some time, e.g. when in storage,we recommend switching it on for at least two hours to allowany condensation to evaporate and to move the bearings.Malfunction/fault Possible cause Possible remedyImpeller notrunning smoothlyImbalance in rotatingpartsClean the device;replace it if imbalancepersists after cleaning.Make sure noweight clips areremoved duringcleaning.Motor not turning Mechanical blockage Switch off, isolatefrom supply andremove mechanicalblockage.Line voltage faulty Check line voltage,restore powersupply, apply controlsignal.Item no. 50831-5-9970 · ENU · Change 90549 · Approved 2017-03-17 · Page 10 / 12ebm-papst Mulfingen GmbH & Co.
